  • Eastwood Basics to Metal Buffing Tech Demo Q&A Answers

    We recently held a live tech demo on the basics to buffing metal. I gave some insight on the basics, tips, tricks, and safety when buffing. We had a great response for the Q&A and ran out of time to answer all of the questions. I wanted to answer all questions we missed live, so below are the answers for any we missed. Thanks for watching and drop us a line if you have an idea for another live tech demo! -Matt/EW

    Datest41- How do you take pits out of chrome plated pot metal?

    worker9270- How d you take pits out of chrome?

    We had a lot of questions about this. The short answer to this is that you can't remove pits or rust or major imperfections in chrome. Chrome is a coating and much like paint once the rust or pitting is coming up from under the coating it can't be fixed without removing the coating and treating the surface. Minor spotting can be polished out of chrome, but major defects like pits, rust, flaking, etc can not be fixed with out stripping and chroming the part again.

    alanbarclay73- Any tips for cleaning and protecting a rusty cast exhaust manifold?

    The best way to clean a rusty cast manifold is to media blast it, then apply one of our exhaust manifold paints

    swayman007- Can you use any of these to polish out scratches in glass?

    The blue "plastic" compound may help with some hazing, but scratches (especially if you can feel them with your fingernail) are tough to get out of glass. Our Pro Glass Polishing Kit for Deep Scratches will be the best bet in that situation.

    xplodee- Do you ever cheat on super soft metals by starting with emory compound rather than sanding?

    I'd be a liar if I said I haven't! The only thing you have to be careful with is that it is easy to take too much material away when using the buff motor and a heavier compound or more aggressive buff wheel than suggested for that metal. Just be VERY careful when doing that and check your progress often.

    wildfire02- Wouldn't it be better to polish really small parts in a vibratory polisher?

    A vibratory polisher or tumbler works GREAT for small parts, but admittedly it does take quite a long time to get parts mirror polished with a tumbler. If you have a big pile of small parts to polish, I'd definitely say use the tumbler, but if you just have a handful or just a couple small items, it might be quicker/easier to use a buff wheel. It really depends on the situation.

    swayman007- Can you use these wheels on a polisher sander for like polishing diamond plate?

    It could be possible, but you have to make sure that the buff wheels can safely mount to your polisher and that the polisher rotates at the correct RPM range.

    Datest41- What sort of wheel is used for step 1, 2, 3 and step 4?

    I covered that in the video, but it's also laid out in a chart in a tech article on or site here: HERE

    mimiof6- Does is matter what rpm the motor is?

    It depends on what you're buffing and the size of the wheel and motor you're using. We recommend 3600 for most metals (lower is acceptable for plated parts and softer metals) and 1800 for plastics with a 10" buff wheel.

    kennyredman- How often do you use a sisal wheel- would it have been appropriate on that rough sandcast?

    The sisal wheel is used for heavy cutting and smoothing metal. It works well for smoothing rough metal when coupled with our greaseless compounds.

    xplodee- the brass parts i polish are antique fans sitting inside?

    It depends on the conditions they are exposed to, but we guarantee at least 3 months, but probably longer if they're inside a climate controlled situation.

    wildfire02- do you have to change wheels with different compounds because of contamination or not mix?

    It's a best practice because it is difficult to get ALL of the traces of old compound off of the wheel and it could be counter-active to the polishing procedure.

    dreamboat77- don't you mean white compound? Rouge is red?

    The white compound is referred to as "White Rouge" throughout the industry. Not sure who started that or why, but there is white AND red rogue compound. Red is generally the final coloring compound and a bit more delicate than the white rouge.

    Datest41- what color is step 2?!?

    It depends on the material that you're buffing or polishing. We have a good breakdown of the steps in the tech article on our site. You can see that here: Here

    swayman007- how do you determine what size wheels to use 6", 8", or 10"?

    It depends on the buff motor that you're using. Check your motor for details on which is best. We have a chart in our buffing tech article on the site. You can see it Here.

    xplodee- What does everyone do to collect the dust from their buffer?

    One idea I didn't hit on during the live feed was that you could let a shop vac run during the buffing process to pick up the dust thrown by the wheel. It isn't as good as a air filtration system, but it is a similar concept.

    JorgeCardoso- I want to see how to work with the expander wheel, do you have any video?

    We do not currently have a video on using the expander wheel. We'll work on getting one put up ASAP!

    bamadio- You sell a 2 speed buffer motor. In what situations do you use each speed?

    The higher speed is used for metal and the lower speed is normally used for plastics and delicate metals or plated parts.

  • Eastwood Live Beginners MIG Welding Demo Q&A- We Answer Your Questions!

    Ever wish you had direct access to an Eastwood Expert to show you how to Do The Job Right?....Recently we held a Live MIG welding Demo where I showed some of the basics of MIG welding and how to correct subpar welds. During the demo we offered a live chat room where an Eastwood Expert answered some basic questions and I also answered some live during the demo. We did run out of time and missed answering some of the questions, so we decided to offer them up here. If you have a question or suggestion for a future Live Demo, please drop us a line!


    1. vmwhitaker Any chance of getting a DVD of this program?
    A: Unfortunately we won’t be offering a DVD of the program, but you can watch the video on our YouTube page: Click Here to Watch

    2. JPower6210 8 - 10 what?
    A: 8-10CFH indoors for general sheet metal or light duty fabrication work. You will need higher gas flow for hard to reach joints, weld positions, heavy fabrication or also outdoors.

    3. waynearny How about some examples of sheet metal weld techniques?
    A:Thanks for the request, we’ll try and work sheet metal welding into our next demo.

    4. leonzak Can you demo sheetmetal?
    A:Thanks for the request, we’ll try and work sheet metal welding into our next demo.

    5. Michaelaw If I am working on car, do I need to worry about gasoline fumes from the tank?
    A: The simple answer is yes. But, most automotive fuel systems are closed and should not be leaking much if any fuel fumes. If you are welding near an area that has a fuel line, or is prone to fuel fume leakage, we suggest shielding over sealing the area and then covering it with a welding blanket.

    6. rwhca if you were to buy one welder for automotive restoration -- MIG or TIG?
    A: For general automotive work MIG is most definitely the best all around machine. TIG welding is very nice and produces clean, slag-free welds, but it requires a lot more technique and preparation to get a clean weld.

    7. TerryJOMT When you ran that last bead, did you move the arc in a circle or a U shaped pattern?
    A: I moved in a circle pattern with the welds in this demo.

    8. amsoilguy Are there guidelines for settings based on metal thicknesses?
    A: Yes, each machine is different and usually there are settings printed on the machine with baselines for each situation. Remember these settings are WITHOUT an extension cord. Also remember settings can change with size of the wire being used.

    9. rubber2theroad see, what's the spray on product name Matt was recommending for flux
    A: I was referring to our Eastwood “Anti-Spatter”. It can be found here: http://www.eastwood.com/ew-paintable-welding-anti-spatter-14-oz-aerosol.html

    10. toddgaron On the gas setting 8-10 CFM or L/min
    A: 8-10CFH indoors for general sheet metal or light duty fabrication work. You will need higher gas flow for hard to reach joints, weld positions, heavy fabrication or also outdoors.

    11. Mreship Thank you, can we talk about a 135 versus a 175 machine?
    A: The 135 can do the majority of your general autobody repair and light fabrication. With proper joint preparation you can do some heavier fabrication, but major chassis and suspension fabrication would be required to use the 175. Additionally the MIG 175 can weld aluminum with the included spoolgun.

    12. rmvlt1100 can the 110 volt welder be used for chassis work?
    A: It all depends on what you’re welding. If you prepare the joint correctly and have correct technique you can do some light to medium duty chassis work. The MIG 175 would handle most all chassis work on an auto with ease.

    13. oneill7777 How do you determine volts & wire speed when welding 2 different thicknesses of metal?
    A: This would more be a matter of technique. I’d adjust the settings to weld the thicker of the 2 pieces and then you want to favor your puddle/heat onto the thicker piece to avoid burning through the lighter gauge piece of metal.
